$ per 1M tokens. Each model uses the provider's cheapest group; the ratio uses the output price

How to check it works

Restart Claude Code and send a message. If it replies and the request shows up in Laozhang API's console, it is using this endpoint.

FAQ

settings.json or environment variables?

settings.json applies every time Claude Code starts, for long-term use; the environment variables apply to the current terminal only, for a quick try.

How do I switch back to Anthropic?

Remove these variables from settings.json (or close the terminal where you set them), then restart Claude Code.

Does my key pass through this site?

No. The page only generates config text and never asks for your key; the key only goes into the config file or terminal on your own machine.
